, To all whom. it may courent.'

Be it known that we, R'oRnRT E. CARLTON and STUART Y. Ummm', citizens ofthe lnitedv States, and residents of Covington, in the county of Kentonand Sta-te of Kentucky, have made certain Improvements in OilingAttachments for Street-Sprinklers, ot' which the following is aspecification.

This invention is an improvement in the application ot oil to thesurfacesof streets or roadways, which is desirable as iswell known forthe laying of dust as well as for ,the hardening ot the road; and theinvention consists in certain novel constructions --'l`he tank hasl anopening provided with a threaded bushing B into which screws the nippleon the connection C, suitable packing being employed at B and the nip-)le t" colinunicatin f with the main tube ("2 midway between the ends oftheV latter. This main tube of the' connection C2 has suitablethreadedor coupling portions C3 and C4 at its ends-so it can conveniently becoupled up with an ordinary garden hose or with the supply pipe of awater wagon or car which latter may be of ordinary construction.,

The nipple.v ("f has longitudimtl ports l .and 2, the Jformerbeingtoward the inlet end of the connection and the latter toward thedischarge end and at their juncture with the main channel 3, `thepassages land 2 are separated by a projecting bridge or abutment- 4which extends slightly intothe main ,channel or passage f3 and operatesto deflect or divert a portion ot the water passing througl the channel.-l down through the passage 1 into the tank, the said passage beingprolonged by a .pipe 5 to a point near the bottom ol the tank so thattht-v portion of water diverted Ifrom the main tube connection will passAunder the body of the oil in the tank and tend to lift the same anddischarge it `through the passage 2 into the main channel 3 on theopposite side of the passage'l so that the portion of oil so discharged.from the tankv will mix with vthe water passing to a dischargeno'zzleand be distributed with such water on` the surface of the street or roadso that'the `Water will' serve to allay the dust and the oil can op.-

erate immediately for its desired pur ose.k f

suitable valve is provided contro ling Asupply pipe. This valve is shownat 6 as a plate pivoted at 7 so-it can be turned to wholly or partiallycut off the'oil discharge passage.

ln operation it will Vbe noticed that the. passage for permitting theflow of 'Water tothe tank coperates with the valved oil n l dischargepassage from the tank and with the main tube of the connection inermitthe4 oil ldischarge passage 2 so as to regulate ithe amountV of oilpermitted to flow to the 'ting a portion of the water supplie to thea."

connection to be diverted for the purpose of forcing a' correspondingquantity` of oil i and it will further be noticed that the` bridge 4which is integral with the nipple C projects into and substantiallyconstricts the bore oi' the connection C and operates to positivelydeflect a portion of thematerial' supplied at C4 down throughthe port 1into the holder A.

We claim:

The combination in a sprinkler, of a tank, a connection having a' maintube and a nipple depending therefrom and screwing .into the tank, saidnipple'having two ports extended longitudinally through it parallel witheach other and with the axis of the nipple, a discharge pipe connectedwith the nipple and depending therefromY into tite tank andcommunicating at its upper end with one of the nipple ports, a valve'latthe lower end of and controlling the other one of said ports of thenipple whereby the said Amd?" `tending partially acrossend substantially-I0 nected with the depending tube whereby to valve will be incldsedwithin the tank when positively deflect material supplied to the thelatter is applied lo the nipple but will i niain lube through the Saidport and the de be exposed for manipulation when the. tank pending'lube,l substantially as and for the and nipple are detached, the saidnipplef ppi-poses set forth.
